The 3D modeling of the process plan of the shipyard is an important work for BIM design. NDRI developed the shipyard parametric modeling software based on SketchUp, which enables the process engineers to take part in the BIM design.

This paper describes the development process of the CAD software for pipe workshop technology design. The software is developed under Asp. net, Office VBE and SketchUp API. This software has the function of design calculation, knowledge database and 3D modeling. The object of the software is to guide the technology design and improve the level of computer application
